How to propagate configuration files to Controller Members from Collective Controllerm in WLP Cluster

I have a Liberty cluster with 10+ Controller Members in it. And I deployed an application into this cluster and now have a new configuration file name myapp.server.xml which need to be included in server.xml. That means I need to update the server.xml of each Controller Members in this cluster by adding following items:

Since there are 10+ members in this cluster, and update server.xml one by one is low efficiency as I need to log in each node and do updates. So is there anyway to propagate the updates to each node from Collective Controller? Both command or API is OK.
